Make parent_class static. Sun Nov 5 04:24:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcellrenderertextpixbuf.c: Make parent_class static. Tue Sep 19 10:54:22 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext*.[ch] gtk/gtkimmulticontext.[ch] gtk/gtktextlayout.[ch] gtk/gtktextview.c gtk/gtkentry.c: Add support for positioning the cursor within the preedit string. Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

urg, removed implementation of gtk_marshal_VOID__INT_INT_INT_INT. if Wed Oct 25 20:47:41 2000 Tim Janik <timj@gtk.org> * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): urg, removed implementation of gtk_marshal_VOID__INT_INT_INT_INT. if people do that, couldn't they at least give it a non-standard name? * gtk/gtktextlayout.c: arg! yet another implementation of gtk_marshal_VOID__INT_INT_INT_INT(), is this a conspiracy? * gtk/gtktextbuffer.c: gotcha! captured a vagabonding gtk_marshal_VOID__INT_POINTER_INT() implementation, braught it back home. now i know this _is_ a conspiracy. * gtk/gtkwidget.c (gtk_widget_class_init): marshaller fixups for ::state-changed. * gtk/gtkaccelgroup.c (gtk_accel_group_create_remove): (gtk_accel_group_create_add): marshaller signature fixups. * gtk/gtklistitem.c (gtk_list_item_class_init): signal creation fixups, pass in GTK_TYPE_SCROLL_TYPE instead of GTK_TYPE_ENUM. * gtk/gtkobject.[hc]: removed GTK_CONNECTED flag, it's not valid anymore. Tue Oct 24 23:59:21 2000 Tim Janik <timj@gtk.org> * docs/reference/Makefile.am: disabled SUBDIRS for the moment, since due to the signal system changes, it wouldn't build currently. to be fixed soon. * docs/Changes-2.0.txt: GtkSignal/GSignal updates. * gtk/gtkwidget.c: ::direction_changed takes an enum as argument, so it needs gtk_marshal_VOID__ENUM() instead of gtk_marshal_NONE__UINT(). * gdk/gdk*.c: adapted type registration functions. * gtk/gtkbindings.c: * gtk/gtkaccelgroup.c: operate on GSignalQuery, GtkSignalQuery is gone. * gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType. * gtk/gtkobject.c: (gtk_object_destroy): (gtk_object_shutdown): fixed recursion guards. basically we have to catch the case where any of GObject.shutdown() or gtk_object_destroy() is called during ::destroy, and avoid recursion there. * gtk/gtktypeutils.c: * gtk/maketypes.awk: awk-script hackup to provide gtk_type_init() with boxed_copy/boxed_free. this needs a more general solution based on a publically installed code-generator utility. * gtk/gtktypeutils.[hc]: compat aliased GTK_TYPE_BOXED to G_TYPE_BOXED, glib's gobject has support for that now. define GtkSignalMarshaller in terms of GSignalCMarshaller. Mon Oct 23 09:36:42 2000 Tim Janik <timj@gtk.org> * gtk/gtksignal.[hc]: * gtk/gtkmarshal.[hc]: * gtk/Makefile.am: generate marshallers with glib-genmarshal and don't compile gtkmarshal.c on its own anymore, just include it in gtksignal.c. removed #include <gtkmarshal.h>s all over the place, gtksignal.h takes care of that. * *.c: marshaller name fixups. * gtk/gtkmarshal.list: added a comment briefing the format. Sun Oct 22 23:14:39 2000 Tim Janik <timj@gtk.org> * gtk/gtksignal.[hc]: nuked old implementation. we mostly have compatibility macros here now. more specifically, most of the API is preserved (yes, _most_, nonwithstanding the following exceptions listed, the API is stil lHUGE ;) things that got removed completely: GtkSignalQuery, gtk_signal_query(), gtk_signal_n_emissions(), gtk_signal_n_emissions_by_name(), gtk_signal_handlers_destroy(), gtk_signal_set_funcs(), gtk_signal_handler_pending_by_id(), gtk_signal_add_emission_hook(), gtk_signal_add_emission_hook_full(), gtk_signal_remove_emission_hook(). non-functional functions variants: gtk_signal_add_emission_hook(), gtk_signal_remove_emission_hook(). the GtkCallbackMarshal argument to gtk_signal_connect_full() is not supported anymore. (gtk_signal_compat_matched): new internal function to aid implementation of the compatibility macros, it provides functionality to block/unblock/disconnect handlers based on func/data. * gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType, * *.c: adaptions to new type registration API signatures. Fri Oct 20 15:26:33 2000 Tim Janik <timj@gtk.org> * gtk/gtktypeutils.[hc]: removed G_TYPE_GTK_POINTER cludge.
